So I’m fairly new to diesels, currently have a 19 L5P, love the truck, minimal upgrades. I have a huge problem though, getting ready to PCS to Korea for a year, can’t take my truck, but was driving, not getting crazy or anything going up a slight hill and my boost tube blew off on the high side of the passenger side, not sure if that’s the hot side or what, but when that happened, obviously my truck sputtered and lost all power, then shut off, I had it towed home and was happy to see that it blew there, it’s way simpler than the intercooler side, long story short, I put it back together, tightened the shit out of it, and was expecting no more issues, but my I dash is still reading 0 boost pressure, and I have the same symptoms, have checked every other coupling and none of them were loose. My question is, where should I start next, do I just take it to a shop, I’m pretty mechanically inclined, but there is so much extra shit under these hoods and everything seems electrical…what could have cause the tube to blow apart in the first place? I wasn’t on it, I might of had like 15psi of boost, just cruising, it was a pretty rough road so wasn’t on it
In need of some guidance

Did you clear all the codes? And I mean all of them from every module. Sometimes just the ecm is not enough as the tcm, bcm and gpcm will house them and keep you in limp mode.
Just reading the gauge on the iDash…it won’t run more than maybe two seconds before dying
It never threw any codes until I had it towed home and the batteries were dying trying to start it, buddy told me something similar happened to his, had it towed to the dealer and all they did was replace the batteries, so currently putting 600 bucks worth of bats in, I’m kinda doubtful that it will help, but I tested them in the truck and as soon as I put a load on the tester, they dropped to less than 300 cca, so they needed replaced anyways I guess, but my assumption is if they were not strong enough to control the turbo, then it would have thrown a code for my charging ststem
See what new batteries do. These trucks will NOt run if unmetered air is coming into the engine. May need to boost leak test after turbo and smoke test after maf to turbo.
Yeah, why is all my exhaust pressure coming through that though instead of the actual exhaust….is the filter 100% blocked? Is that what’s causing no pressure on my boost gauge….im so fucking lost
To plug it up that fast, there’s more going on that either what you know or what we can understand for what’s gone on.
At this point, that pipe needs to be repaired (don’t run it anymore) and you need to see if your turbo has failed. Then more diag needs to be done from there if the turbo didn’t fail.
